Application tiled February 24, 1886. Serial No. 193,087. (I No model.)Patented in Germany May 12, 1885, No. 33.219; in England I l July 1 6,1885, No. 8,615, andiu Belgium December 14, 1885, No. 71,223.

To aZZ whom it may concern:

Beit known that I, RUDOLF KULLIG, engineer, a subject of the King ofPrussia, and a resident of Elberfeld, in the Kingdom of Prussia,Germany, have invented some new and useful Improvements in Steam-Traps,of which the following is a specification.

The object of these improvements is to remove the drawbacks contained inthe so-called Royles Steam-Traps,77 which have been used hitherto.

In Royles apparatus, working with a bellshaped iioat, the lateralsteam-inlet tube forms also the axis of the bell doat, and the steamtubeand the iioat form together a stop-cock in this manner, that by therotating 'of the bell-float the steam-inlet tube is opened and closed,as if by a stop-cock. This method of closing the steam-tube, caused, asjust said, by the bell-iioat rotating on its axis, has the/ one greatdrawback that the closing soon becomes loose and-admits steam, and isparticularly unreliable under high steam pressure. In the improvementdescribed hereinafter this evil is avoided by applying a valve in lieuof a stop-cock for closing the outlet-tube for the condensed water. Itis applied in such a way that the bell-lioat, when rising,I presses thevalve firmly on its seat, which is formed bythe end of the steam-tubeand closes the steaminlet steam-tight.

The improvement is represented in Figures l to 6 of the drawings.

Like letters indicate like paris in all the iigures.

Fig. l is a vertical section through the line A B when the bell-float isin its highest position, in which case valve o is likewise in itshighest position and the inlet-tu 'oe for the condensed water is closed.Fig. 2 is averticalsection through the line A B when the bell-float isin its lowest position, in which case valve@ islil'ted from itsseat-that is to say, from the end f of the steam-tubef, and thecondensed water collected in the tube f escapes in the bellfloat and theVessel M. Fig. 3 is a vertical section through the line C D. Fig. 4 isatop view of the steam-trap, the lid or cover m and the air-escape slideb being both removed. Fig. 5 (a section through the line AB) shows apart 0f the bell-float c, with the regulating-screw e ,for valve o andbalance-weight c, the steam-- ytube f, with its end f. The steam-tubefisy connected at its other end with the steam-conduit, out of whichcomes the condensed water that collects in tubef. Fig. 6 shows a sectionthrough the line E F, the tubef, with the top View of valve o.

The construction and arrangement of the parts is as follows:

M is a vessel open on top, with a steamtube ff on the one side and anoutlet-aperture on the other side. The vessel can be covered by aremovable lid or cover, m, to prevent dirt, &c., getting into it. Theend f of the steam-tubef is bent downward, and into it is tixeda movablevalve, o, which can either close or open the steam-inlet aperture. Valven is made movable in the direction of endf of the steam-tube and theguides that are attached to the valve and that encircle the end f of thesteam-tube keep the valve always in the proper direction, so that ittits tight onto the endf of the steam-tube every time if it is movedupward.A This apparatus consists, fur- 7 ther, of a bell-Boat, c, Whichis supported on the one side by bearers t and by means of axle s, roundwhich it rotates. The bell-float c rests on the other side, as will beseen in the drawings, Fig. 2, on the bottom of the vessel M. In case thebell-doat is made of cast-iron and requires balancing it can be providedwith a balance-weight, a. This bell-float has on itsl upper side, justlike the drain for the'condensed water in Boyles apparatus, two littleslits, o, which are covered by the littleslide b,

attached to the rod n, and are always kept closed when the apparatus isworking. These slits answer the same purpose as those in .Roylesdrain-that is to say, they allow the air to escape when the apparatus isstarted.' This is done in the well-known way by lifting the slide b onceonly.

w x are arms riveted fast to the bell-Heat c. The left arm bears thebalance-weight a, and the right arm the screw e, which can be screwedeither higher or lower in arm x, according as may be necessary. Thisscrew serves as an adjusting-screw to make the valve o close properly inthe desired position.

, The way in which the apparatus operates is as follows: When theapparatus is not work- IOO ing, the parts are in the position indicatedin Fig. 2. When the tube ff is brought in connection with thesteam-conduit, which is not represented in the drawings, the steampasses through the open aperture of the tube f', fills f the space inthe bell, and forces the water contained in the latter downward and outof it. The bell begins to oat and to rise, and the axle s forms therotation-axis; but while the bell rises, the screw e, attached to arm wof the float, knocks against the valve 'u and presses it upward untilthe valvecis laid hard against tube f and shuts the open end ofitcompletely. No steam can then escape from the tube f f. The steamconned in the bell keeps it in its raised position, and valve lv is shutby screw e. When the steam begins to condense, bell c will sink again,and valve o will be lifted oi its seat f', for screw e will relax in itspressure, whereas the pressure coming out of tube f will force the valve'v downward. If there is any condensed water in the tubeff, it will thenflow out; but this water'will not cause any alteration in the momentaryposition of the float, for the-condensed water cannot possibly raise theoat. The oat is not raised .again before the condensed water has run outand steam begins to escape through tube The bell rises again at once,valve v is again liftedthat `is to say, tube f is shut again-and theescape of steam prevented. The condensed water flows out from the vcsselM through the aperture g. Screw e serves to regulate the proper closingof the valve v.

What I claim, and desire to secure by Letters' Patent of the UnitedStates, is-

In steam-traps, the combination of a steamtube, f, its open tube end fbent downward, with a valve, 0, which is movable toward the said opentube endf, and can open and shut it as necessary, and a rotatingbell-float, c, whichis suspended in the vessel M and has an arm, w,which closes the valve v.
